IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
(For units with GFCI)
WARNING – This product is provided with a ground-fault circuit interrupter locat-
ed on the front panel of selected swim spas and on the power cord of 120 volt
convertible spas. The GFCI must be tested before each use. With the product
operating, open the service door. When the product stops operating, this merely
indicates that the door is equipped with an electrical interlock. Next, push the
test button on the GFCI and close the service door. The product should not oper-
ate. Now open the service door, push the reset button on the GFCI and close the
service door. The product should now operate normally. When the product fails
to operate in this manner, there is a ground current flowing indicating the possi-
bility of an electric shock. Disconnect the power until the fault has been identified
and corrected.

DANGER – Risk of Accidental Drowning. Extreme caution must be exercised to prevent
unauthorized access by children. To avoid accidents, ensure that children cannot use
this spa unless they are supervised at all times.

DANGER – Risk of Injury. The suction fittings in this spa are sized to match the specific
water flow created by the pump. Should the need arise to replace the suction fittings
or the pump, be sure that the flow rates are compatible.

Never operate spa if the suction fittings are broken or missing. Never replace a suction
fitting with one rated less than the flow rate marked on the original suction fitting.

DANGER – Risk of Electric Shock. Install at least 5 feet (1.5m) from all metal surfaces.
As an alternative, a spa may be installed within 5 feet of metal surfaces if each metal
surface is permanently connected by a minimum 8AWG (8.4mm2) solid copper conduc-
tor to the wire connector on the terminal box that is provided for this purpose.

DANGER – Risk of Electric Shock. Do not permit any electric appliance, such as a light,
telephone, radio, or television, within 5 feet (1.5 m) of a spa.

WARNING – To reduce the risk of injury:

a) The water in a spa should never exceed 40˚C (104˚F). Water temperatures
between 38˚C (100˚F) and 40˚C are considered safe for a healthy adult. Lower
water temperatures are recommended for young children and when spa use
exceeds 10 minutes.

DO NOT DIVE. 5

SAFETY INSTRUCTIONS

(CONT.)
b) Since excessive water temperatures have a high potential for causing fetal
damage during the early months of pregnancy, pregnant or possibly pregnant
women should limit spa water temperatures to 38˚C (100˚F).

c) Before entering a spa, the user should measure the water temperature since the
tolerance of water temperature- regulating devices varies.

d) The use of alcohol, drugs, or medication before or during spa use may lead to
unconsciousness with the possibility of drowning.

e) Obese persons and persons with a history of heart disease, low or high blood
pressure, circulatory system problems, or diabetes should consult a physician
before using a spa.

f) Persons using medication should consult a physician before using a spa since
some medication may induce drowsiness while other medication may affect
heart rate, blood pressure, and circulation.

(For spas with a gas heater)

WARNING – Risk of Suffocation. This spa is equipped with a gas heater and is
intended for outdoor use only unless proper ventilation can be provided for an
indoor installation.

ELECTRICAL INSTALLATION REQUIREMENTS

ELECTRICAL INSTALLATION REQUIREMENTS
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORMATION
BEFORE INSTALLATION BEGINS

Electrical connections made improperly, or the use of wire gauge sizes for incurring
power which are too small, may continually blow fuses in the electrical equipment box,
may damage the internal electrical controls and components, may be unsafe and in any
case will void your warranty.
It is the responsibility of the spa owner to ensure that electrical connections are made by
a qualified electrician in accordance with the National Electrical Code and any local and
state electrical codes in force at the time of installation.
These connections must be made in accordance with the wiring diagrams found inside
the control box. This equipment has been designed to operate on 60Hz.
alternating current only, 240 volts are required. Make sure that power is not applied
while performing any electrical installation. A copper bonding lug has been provided on
the electrical equipment pack to allow connection to local ground points. The ground
wire must be at least 8 AWG copper wire and must be connected securely to a grounded
metal structure such as a cold water pipe. All Master Spas equipment packs are wired for
240 VAC only. The only electrical supply for your spa must include a 50 AMP switch
or circuit breaker to open all non-grounded supply conductors to comply with section
422-20 of the National Electrical Code. The disconnect must
be readily accessible to the spa occupants, but installed at least five feet from the spa. A
Ground-Fault Circuit Interrupter (GFCI) must be used to comply with section 680-42
of the National Electrical Code. A ground fault is a current leak from any
one of the supply conductors to ground. A GFCI is designed to automatically shut off
power to a piece of equipment when a ground fault is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground (6 AWG copper)
8 AWG copper ground.
Route the cable into the equipment area for final hook-up to terminals inside the con-
trol panel. The spa must be hooked up to a “dedicated” 240 volt, 50 amp breaker and
GFCI. The term “dedicated” means the electrical circuit for the spa is not being used for
any other electrical items (patio lights, appliances, garage circuits, etc.). If the spa is con-
nected to a non-dedicated circuit, overloading will result in “nuisance tripping” which
requires resetting of the breaker switch at the house electrical panel.

SITE PREPARATION / GENERAL GUIDELINES

Portable spa installation is simple when properly planned. It is important that you read the following
information carefully and consult with your Master Spas dealer.
1) Access - The actual dimensions of your new spa will determine the amount of space that is needed in
moving the spa from curbside to its final installation area. Be sure to measure side yard dimensions,
gates or doors and vertical obstructions such as roof overhangs and overhead cables. Any other space
limiting obstacles such as trees or shrubs must be evaluated.
2) If the spa is being installed indoors, dimension limitations such as stairs, ceilings and walls must
be taken into consideration. Please have your Master Spas dealer or delivery service review site
or installation plans prior to delivery.
3) Surface/Pad Requirements - When your new spa is filled with water and bathers, it may weigh as
much as several tons. It is imperative that the base beneath the spa can support the entire weight.
The spa must be on a uniformly firm, continuous, and level surface. The recommended foundation
is a concrete pad with a minimum thickness of four (4) inches with steel reinforcement bars crossed
throughout the pad.

IMPORTANT
When installing your spa indoors, on a wood deck, or balcony, the same load requirements must
be met. Total load may be as much as 90 pounds per square foot. You should speak with a qualified
contractor or your local building department to confirm that your surface is adequate for supporting
a spa. Be sure to locate your spa so that equipment remains above grade and is not subject to
flooding.
The equipment side(s) of the spa must be accessible in the event that future service is needed. Periodical
maintenance checks require entry into the equipment bay. When possible, it is wise planning for the
future to leave 2 feet of access to all sides of the spa in the event your spas plumbing requires
maintenance. Your spa warranty does not cover the cost of providing access for service.

GENERAL CONSIDERATIONS FOR OUTDOOR INSTALLATION
Again, proper planning will increase your total enjoyment factor with your new spa. Listed below are
some additional items to consider when planning your installation.
• How spa will complement landscaping • Getting to spa from house and return
and vice versa • Proximity to dressing rooms and bathrooms
• iew from inside spa and view of spa from
V • Storage for spa chemicals
inside of home
• Local building codes (if applicable)
• Exposure to sunlight and shading from trees
• Power cable
• Privacy

GENERAL CONSIDERATIONS FOR INDOOR INSTALLATION
Installing your spa indoors creates an entirely different set of considerations. With proper planning,
no matter what room your spa goes in, it will be your favorite room.

• Work with your Master Spas dealer and • ventilation fan may be necessary due
A
contractor to insure all local building, electrical to high humidity created by your spa
and plumbing codes are met • inished material in your spa room should also
F
• lan for a floor drain to drain off excess water
P be capable of withstanding increased humidity
or for draining and cleaning your spa

INSTALLATION INSTRUCTIONS

1. Put spa in final position that allows for access to equipment and spa components.
2. Remove front side panel (This is the side where the main topside control panel is located) so
electrical can be hooked up to the spa system pack. Panels are removed by unscrewing the screws
in the corner sections and then lifting up the panels out of the retaining tracks. NOTE: If your spa is
equipped with Master Select panels, you will need to remove the Phillips mounting screws instead
of the corner screws.
3. Be sure all pump and heater unions are secure. Each pump has 2 unions and the heater has
2 unions. A newly delivered spa may have loose unions caused in transporting the spa. Check
that all slice valves are open, in the up position. The slice valves may become closed during
transportation of the spa.

INSTALLATION INSTRUCTIONS

7. It may be necessary to bleed air from the pump(s) on your spa if, after start up, your spa pumps
do not operate.
Due to the nature of water flow and hydro-therapy pumps, please be advised that air locking of
pumps may occur. Master Spas has taken measures to reduce the possibility of this, but it still may
occur, especially after refilling a spa. This is not a service covered under warranty.
To relieve and airlock, loosen the union on the discharge of the pump (see arrow on picture of
pump below). Water should leak out. Tighten the union and test the pump for proper jet flow.
If needed repeat process.

8. Adjust water chemistry according to the instructions provided in the “Spa Water
Maintenance Section”.
9. Your spa water will heat approximately 4 -7 degrees per hour. This varies depending on the size
of the spa. Step into the soothing waters of your Master Spa!

WATER CHEMISTRY TERMS YOU SHOULD KNOW
Before jumping into the Spa Water Maintenance, here are some terms to help you.

1. Parts per million, or ppm: This is a form of measurement used in most pool or spa chemical
readings. Best described as any one million like items of equal size and make up, next to one
unlike item , but of equal size. This would be one part per million.
2. Average size spa: What is it? The national spa and pool institute (NSPI) states; 350 to 400 U.S.
gallons is average. As a general rule, chemical dosages are the same for any spa between 100
and 500 U.S. gallons. Spas over 500 U.S. gallons the dosage would be double. Under 100 U.S.
gallons would be on a case by case basis.
3. Total Alkalinity: This is a measurement of the ability of the water to resist changes in pH. Put
another way, it is the water’s ability to maintain proper pH. Total alkalinity is measured in parts per
million from 0 to 400 plus, with 80 to 150 ppm being the best range for spas. With low alkalinity,
the pH will flip, or change back and forth, and be hard to control. With high alkalinity it becomes
extremely difficult to change the pH.
4. pH or potential hydrogen: This is a measurement of the active acidity in the water, or it is
the measurement of the concentration of active hydrogen ions in the water. The greater the
concentration of active hydrogen ions, the lower the pH. pH is not measured in parts per million,
but on a scale from 0 to 14, with 7 being the neutral. In spas when ever possible, a measurement
between 7.2 and 7.8 is best. Whenever possible, it should be between 7.4 and 7.6. With low pH,
the results can be corroded metals, etched and stained plaster stained fiberglass or acrylic, eye /
skin irritation, rapid chlorine or bromine loss, and total alkalinity destruction. With high pH,
the results can be cloudy water, eye / skin irritation, scale formation and poor chlorine or
bromine efficiency.
5. Shocking: This is when you add either extra chlorine (superchlorinate) by raising the chlorine
level above 8 ppm, or add a non-chlorine shock (potassium monoperoxysulfate or potassium
monopersulfate) to burn off the chloramines or bromamines. A non-chlorine shock acts by
releasing oxygen in the water, which serves the same function as chlorine. The advantage to
using non-chlorine shock, is you can enter the water within 15 minutes after shocking. Using
chlorine, you must wait until the total chlorine reading is below 5 ppm. One thing to remember,
a non-chlorine shock will not kill bacteria or disinfect.
6. Sequestering: This can be defined as the ability to form a chemical complex which remains in
solution, despite the presence of a precipitating agent (i.e. calcium and metals). Common names
for sequestering chemicals are; minquest, stain and scale control, metal-x, spa defender, spa
metal gone, (etc.).
7. Filtration: Filters are necessary to remove particles of dust, dirt, algae, etc. that are continuously
entering the water. If the spa is not operated long enough each day for the filter to do a proper
job, this puts a burden on the chemicals, causing extra expense. Filtration time will depend on the
spa size, pump and filter size, and of course, bather load. A spare cartridge should be kept on
hand to make it easy to frequently clean the cartridge without the need for a long shut down. This
will also allow the cartridge to dry out between usages, which will increase the cartridge life span
as much as twice. Replace the cartridge when the pleats begin to deteriorate. Cartridge cleaning
should be done a minimum of once a month. More often with a heavy bather load.

WATER CHEMISTRY TERMS YOU SHOULD KNOW
Before jumping into the Spa Water Maintenance, here are some terms to help you.

8. Sanitizers: This is what kills the germs and bacteria that enter the water from the environment and
the human body.
A. Chlorine
1. Only one type is approved for spa use. Sodium dichlor which is granular, fast dissolving and
pH neutral chlorine.
2. Chlorine is an immediate sanitizer.
B. Bromine (Note: Bromine use is not recommended with Eco Pur filters.)
1. Two types of tablets.
a. Hydrotech
b. Lonza
2. Bromine is a slow dissolve chemical and may take a few days to develop a reserve
or reading in the water.
9. Total dissolved solids (TDS): Materials that have been dissolved by the water. i.e. Like what hap-
pens when you put sugar in coffee or tea.
10. Useful life of water (in days): Water should be drained at least once every 180 days. Useful life may
vary by usage and bather load.
11. Defoamer: Foaming may be caused by body oils, cosmetics, lotions, surface cleaners, high pH or
algeacides as well as other organic materials. Low levels of calcium or sanitizer can also cause
foaming. Also, double rinse your bathing suits as they will hold residual soap after being washed.
12. Calcium hardness: Water that is too hard (over 250 ppm) can promote scale formation in
components and on spa surface. Water that is too low (below 180 ppm) may also shorten
the life of metal components on the spa.
NOTE: Always leave spa cover open for 15 minutes after adding chemicals to prevent the off gas
from damaging your spa cover, spa pillows and other critical parts.

Spa Water Maintenance

* All Legend Series Spas use the ECO PUR filter(s). This section pertains specifically to maintaining water
chemistry in spas that have the ECO PUR filters.

SPECIAL NOTE
ECO PUR™ water filter system is designed to reduce the use of chemicals in your spa. You will still be
required, periodically, based on usage to add a small amount of chlorine to oxidize organic compounds
in the water. The ECO PUR™ filter system will not eliminate the need to maintain proper water
chemistry but can make the maintenance a more natural experience.

Note: Eco-Pur filters are not recommended for use with Bromine. This manual references bromine as well
as chlorine in case you decide to remove the Eco-Pur filters and sanitize your spa with bromine. Consult
your dealer for additional information.

Master Spas, Inc. products are not designed to be used with Biquanides. These chemicals are found in
SoftSwim® and Baqua Spa® products. Due to adverse effects from these types of sanitizers, the use of
these products may void the spa warranty.

DO NOT DIVE. 23

WATER QUALITY MAINTENANCE START-UP

For ECO PUR™ Water Filter System
Step 1: Your spa should be filled using a Pre-filter, which can be obtained from your local dealer.
This Pre-filter will help remove many of the minerals existing in the water, which will make
adjusting the water balance easier after a new fill.
Step 2: During the initial filling of the spa, add a sequestering agent to combat suspended minerals
in the water. The agents are sold under many different names such as Mineral Clear, Stain
and Scale, and other brands. Allow water to circulate and filter for at least 12 hours before
adding any other chemicals.
Step 3: Test water for pH, total Alkalinity, and Calcium hardness. The pH should be 7.2 - 7.8 and
the total Alkalinity 80-150 PPM. Calcium hardness levels should be maintained between 150
and 250 PPM (part per million).
Step 4: Adjust pH, total Alkalinity (TA) and Calcium hardness utilizing the directions on the chemical
bottles provided by your dealers start up kit.
Step 5: It may be necessary to retest and add additional chemicals to get to the proper levels
in Step 3.
Step 6: Add 2 oz. of concentrated chlorinating granules (sodium Dichlor-s-triazinetreone) per 500
gallons on initial start up to begin sanitizing the spa water. It is important not to add the
chlorinating granules until the pH, alkalinity and calcium hardness have been adjusted to
their proper levels.

SPECIAL NOTE:
We recommend a minimum level of 1.0 ppm residual chlorine be maintained in the spa water.
* It may be necessary to rinse your filters within the first few days after filling your spa to ensure that
they are not restricting water flow due to the initial removal of heavy contaminents in source water.

THE ADVANTAGES OF ECO PUR™ filtration

• Helps remove calcium carbonate and hydrogen sulphide from spa water to protect heaters
and equipment from precipitation.
• Helps stabilize the pH and alkalinity of the spa water.
• Helps reduce chemical usage and still provide safe odor-free water.
• Helps deplete excess chlorine after chemical shock to prevent damage to skin, hair, and swim wear.
• Helps to produce ultra clean and clear water.

SPECIAL NOTES
The ECO PUR™ filter system will not oxidize organic compounds and will require periodic doses of
chlorine to assist in the sanitization and oxidation processes required to maintain clear spa water.
• ECO PUR™ filter system will not alter the ph of spa water. The ECO PUR™ filter system will
actually aid in stabilizing the ph. ECO PUR™ does not alter the (TDS) total dissolved solids.
• he main function of the ECO PUR™ filter system is to provide clean and clear spa water.
T
Proper chemical balance and filtration are also key components in maintaining healthy spa
water. Always ensure that the ph and total alkalinity of the spa water is checked and balanced
at all times. To ensure proper filtration, clean the outer filter cartridge with a “filter cleaner”
every 30 days and rinse the ECO PUR™ cartridge with a hose to remove any buildup of
containments. (Do not soak the ECO PUR™ cartridge in filter cleaner.) If water appears
to be visually cloudy, dull, or has an odor, shock the spa water with 2 ounces of chlorine
to remove excessive containments.

DO NOT DIVE. 25

WATER QUALITY MAINTENANCE SCHEDULE-ECO PUR™

BEFORE EACH USE
Check spa water with a test strip for proper sanitation levels and adjust accordingly to the proper levels.

ONCE A WEEK
Add 3 Tablespoons of a non-chlorine shock or 1 tea spoon of Dichlor to spa per 250 gallons.

3 TIMES A WEEK
Test water using chemical test strips. Adjust sanitizer, pH and Alkalinity accordingly.

ONCE A MONTH*
Soak your filter elements overnight in a bucket with spa Filter Cleaner and then rinse with clean water
before re-inserting. (The ECO PUR™ mineral element should never be cleaned in a filter cleaner. Just
rinse with water.)

EVERY 180 DAYS
Drain and refill your spa, replace with a new ECO PUR™ element, repeat start up procedure.

AFTER EACH USE
Add 1 tablespoon of non-chlorine shock or 1/3 teaspoon of Dichlor to spa per 250 gallons.

AS NEEDED
If water looks hazy, shock treat with 1 teaspoon of Dichlor per 500 gallons.

* These are general recommendations for water quality maintenance that may vary by usage and or
bather load. Depending on bather load and frequency of use, drain and refill times may vary as well
as the frequency of cleaning your filters.
* Foam Gone may be used when excessive foaming occurs. Be sure to use only a drop or two at a time.
Over use of Foam Gone will result in cloudy, milky water.

NOTE: As an alternative to non chlorine shock, Dichlor may be substituted.
1 tsp. Dichlor = 3 tablespoons of non chlorine shock

USE ONLY SPA CHEMICALS
(some pool chemicals are not suitable for spa use).
* when cleaning filters, be sure to never have the pumps (including the circulation pump)
running without the filters in place. Failure to do so may result in debris in the pumps causing
unwarranted damage.

SPA WATER MAINTENANCE - START-UP
For Spas without Eco Pur™ Filtration System

1. Read the spa owners manual first.
2. Clean the surface with a spa general purpose cleaner or wipe down with a clean wet towel.
3. Begin filling the spa with fresh water. If possible, do not use softened water.
4. When the spa has 2 to 4 inches of water on the bottom, add the recommended amount of
a sequestering chemical for that size spa. See the chemical bottle for correct amounts.
5. When the spa is full, run the pumps on high speed for 30 minutes without air controls open. This
will give the sequestering chemical time to mix well with the water. Allow sequestering chemical
12-24 hours to properly filter in the water before proceeding with any further steps.
6. Using test strips or a test kit, test for total alkalinity, and adjust if necessary to between 80
to 150 ppm using the pH / alkalinity increaser or decreaser 1oz. at a time. Wait 15 minutes,
retest, and adjust if necessary. The pump should be running on high speed during this time
without air controls open.
7. Using test strips or a test kit, test for pH, and adjust if necessary to within the 7.2 and 7.8
range using the pH / alkalinity increaser or decreaser 1/2oz. at a time. Wait 15 minutes, retest,
and adjust if necessary. The pump should be running on high speed during this time, without
air controls open.
8. Add the sanitizer of choice, following label directions. If chlorine is used, broadcast the
recommended amount across the surface of the water, with the pump running on high speed.
Wait 15 minutes, retest, and adjust if necessary to a total chlorine reading of 1 to 3 ppm. If bro-
mine is used, add bromine tablets to the bromine feeder following label directions. With the pump
running on high speed, add 2oz. of sodium bromide, and shock the spa with 2oz. of non chlorine
shock. It may take several days adjusting the bromine feeder to obtain a total bromine reading of 3
to 5 ppm. A bromine reading may not be obtained on the first day.
9. If any foam develops, add a defoamer at the base of the problem area. Use only enough defoamer
to get rid of the foam. This is usually one or two drops Do not pour large amounts of defoamer
into water.
10. Wait two days, and begin a three day a week maintenance program.

SPA WATER MAINTENANCE - Schedule

Day One
1. Test and adjust total alkalinity if necessary to between 80 to 150 ppm using the pH / alkalinity
increaser or decreaser 1oz. at a time. Wait 15 minutes, retest and adjust if necessary. The pump
should be running on high speed during this time with the air controls closed.
2. Test and adjust pH, if necessary, to within the range of 7.2 to 7.8 using the pH / alkalinity increaser
or decreaser, 1/2oz. at a time. Wait 15 minutes, retest and adjust if necessary. The pump should be
running on high speed during this time with the air controls closed.
3. Test and adjust sanitizer level. Add chlorine following label directions to maintain a free chlorine
level of 1 to 3 ppm. If using bromine, adjust feeder to maintain a total bromine level of 3 to 5
ppm. Add bromine tablets to the dispenser if necessary, following label directions.
4. Add a water clarifier following label directions. If the spa is equipped with an ozone unit, we
recommend adding an enzyme product in place of the clarifier, following the label directions.
5. Use a small amount of defoamer only if necessary.

Day Two Skip

increaser or decreaser, 1/2oz. at a time. Wait 15 minutes, retest and adjust if necessary. The pump
4. Shock with 2oz. of non chlorine shock, or superchlorinate following label directions. A spa should
be shocked at least once a week even if it is not used. If using chlorine as the sanitizer, the spa
should be shocked whenever a free chlorine reading of 1 to 3 ppm cannot be obtained without
raising the total chlorine level above 5 ppm. Always shock a spa after any heavy bather load.
5. Check filter cartridge and clean if necessary. Clean with cartridge filter cleaner, following label
directions. It is best to have a spare cartridge on hand, to prevent long spa down times while the
cartridge is being cleaned. Never operate your spa without the filters in place.
6. Use a defoamer only if necessary.

Day Six and Seven Skip
With a spa you are working with a small volume of hot water compared to a large volume of relatively
cool water in a swimming pool. Because of this chemicals will have a shorted life span and bacteria
can grow more quickly than in a swimming pool. A spa is less forgiving then a pool and requires that
whatever is put into it have a pH as close to neutral as possible. That is why only chemicals made for
spas should be used.

WHY ARE CHEMICALS IMPORTANT IN A SPA

1. Evaporation:
As water evaporates, only pure water evaporates, leaving the salts, minerals, metals, and any
unused chemicals behind. Adding water adds more salts, minerals, and metals. In time, the water
can become saturated with these dissolved solids and can cause stains or scale to form on the
walls of the spa or a scale build up inside the equipment. Colored or cloudy water, and possible
corrosion of plumbing and fittings may also occur.

2. Heat:
Heat causes much quicker evaporation and also will cause minerals and metals to precipitate
out of solution.

3. Air:
Dust and airborne dirt particles are introduced into the spa.

4. Environment:
The environment surrounding the spa can also impact the water quality. Items such as pollen,
grass, sand, dirt, lawn fertilizer, airborne dust, insects, leaves, and pets can all affect the water
quality of the spa.

Remember:
The maintenance routines set forth in this manual may need to be adjusted depending on how much
the spa is being used.

MAINTENANCE RECOMMENDATIONS

Your spa requires periodic draining and cleaning to ensure a safe, healthy environment. It is recommended
that you clean your spa at least every 180 days. Heavy bather load will require cleaning it more often.

DRAIN YOUR SPA
• See page 13.

CLEAN YOUR SPA SURFACE
• With a soft cloth, wipe down the spa surface with a non-abrasive spa surface cleaner that may
be purchased through your local spa dealer. Do not use paper towels. Be sure to rinse residue from
spa surface.
• f your spa has developed an oily or chalky residue at the waterline it may require special treatment.
I
Consult your dealer.

REFILL YOUR SPA
• Be sure to close the drain valve.
• ill the spa with water and be sure that water level is above the skimmer opening at the minimum
F
safe water level sticker.
• Refer to your spas corresponding start-up section with any questions.

CLEAN YOUR FILTER ELEMENTS (also reference page 61)
The filter elements are one of the most important components of your spa. Not only are they
essential for clean water, but they also extend the life of the spa equipment. Your filter elements
should be cleaned on a regular basis, once a month on average with normal usage. With heavy
use the filters may need to be cleaned more often.
• urn off the spa before servicing filters. Never leave to the spa running when removing the filters.
T
Debris can be pulled into the plumbing system and cause unwarranted damage.
• Remove filter element(s).
• ith a garden hose, spray each element under pressure. Periodically, the elements need to
W
be soaked in a filter cleaner compound. Check with your dealer for details on cleaning and/or
filter replacement recommendations.
• Replace filter elements.
• Be sure water level is adequate.
• Turn spa on.
• Only clean the ECO PUR filter element with water, do not use chemical cleaners.

CARE OF YOUR SPA PILLOWS
• Your spa pillows need to be rinsed periodically to remove any chemical residue. This should help to
eliminate pillows becoming stiff and discolored.
• If spa is not to be used for a period of time, pillows should be removed. Pillow life will be extended.
• lways leave the cover open for 15 minutes in order to prevent off gas from damaging your spa
A
pillows, cover and other critical parts. Signs of off gas damage include but are not limited to pillows
peeling and bubbling, cover failing prematurely, plastics failing, etc.

DO NOT DIVE. 32

MAINTENANCE RECOMMENDATIONS

CARE OF LAMINAR FLOW JETS:
• In order to keep your Laminar Flow Jets operating properly, follow these instructions in sequence:
- Turn off Laminar Flow Jets
- Remove outer ring by turning face counter clockwise
- Remove internal Jet insert with a pair of needle nose pliers
- Clean plastic filter at the back of the Jet insert so all holes are free of debris
- Reinstall Jet insert and outer ring

NOTE: To prevent premature failure of your spa cover, always turn Laminar Flow Jets down so that they
do not hit the cover when the cover is closed. You do not want to completely turn jets off. Doing so
may cause a build up of stagnant water in the water line if not used often.

DO NOT DIVE. 33

WINTERIZING YOUR SPA

Many people find they enjoy using their spa more in the winter than any other time. Your spa is
designed to be used year round in any type of climate.
*However, if you decide you don’t want to use your spa in the winter, you must drain it and follow the
winterizing steps listed below:

1. Drain your spa completely using the drain valve (see “To Drain Your Spa”) or use an inexpensive
submersible pump that you can buy from your dealer or your local hardware store.
2. Use a shop vac to get all standing water out of your unit.
3. Remove access panels from equipment area.
4. Loosen all pump unions
5. Remove winterizing plug from face of the pump(s) where applicable.
6. Using your shop vac in a blowing mode, insert the hose into the nozzle of each jet and blow the
trapped water from the lines into the interior of the spa.
7. After this is completed, use the shop vac to remove any standing water in the spa and in the
equipment area.
8. Clean the spa with a soft cloth and a non-abrasive spa surface cleaner.
9. Replace access panels.
10. Cover spa to prevent water from entering the spa.

*Disclaimer: Master Spas does not recommend winterizing your spa. If you choose to do so,
any damage that may result is not covered under the spa warranty.

MASTER SPA - LEGEND SERIES - CONTROLS

Timeouts refer to a preset length of time that a function is programmed to operate before shutting off
automatically. Certain conditions (filters or freeze) can cause a function to operate longer, while faults
can cause a function to operate for a shorter length of time. The system keeps track of timeouts
regardless of other conditions occurring.
In multi-button sequences, if buttons are pressed too quickly in sequence, they may not register.

Initial Start-up
After power is applied to the spa it will display configuration information. The spa will then go through
its priming mode. This priming lasts approximately 5 minutes. The purpose of the priming mode is to
help insure that the jet pumps have been primed with water and are ready to operate. It may be neces-
sary in some instances to bleed air from the jet pumps in your spa, if after the priming mode the spa
pumps run but do not move water the pump may have an air lock. (See instructions on page 20)
Once the priming mode has been completed the spa will begin to heat and maintain water temperature
in the Standard mode.

Quick Reference LEDs
There are four LEDs on the left side of the panel that offer quick references to what spa functions are
activated. From top to bottom, these lights indicate the following: Filter Cycle 1, Filter Cycle 2, Panel
Lock, Temperature Lock.

L.E.D. Light
Press the “Light” button to turn the light on and off. If you wish to change the “function” of the lights,
turn the lights off, then on within 5 seconds. If you wish to leave the lights in the same “function”
setting for the next use, turn the lights off and do not turn back on for at least 5 seconds.

Circ Pump
Your system may be configured to work in one of three different ways:
1. The circ pump operates continuously (24 hours) with the exception of turning off for 30 minutes
at a time when the water temperature reaches 3˚ F (1.5˚C) above the set temperature (most likely
to happen in very hot climates).
2. The circ pump stays on continuously, regardless of water temperature.
3. The circ pump will come on when the system is checking temperature (polling), during filter cycles,
during freeze conditions, or when another pump is on.
4. If the circulation pump operates for more than 15 minutes without proper water flow, it will shut
down and not operate until power to the spa has been reset.
NOTE: Factory configuration is chosen based on what the majority of users will need. If you would
like your spa to operate in a different configuration setting, your dealer can change your setting
for a fee.

Preset Filter Cycles
On your Legend system, the circ pump, low speed of pump 1, and the ozone generator will run during
filtration. At the start of each filter cycle, the lowest speed of all pumps will run for 5 minutes.
(The following is specific to all systems that are programmed according to time)
There are two filter cycles per day. The start/end times of each cycle are programmable. To program,
set time as instructed above, then press “Program/Mode” to advance to the next setting (or to exit
after the last setting). The default filter cycles are as follows:
The first filter cycle is automatically activated at 8:00 AM and operates the pump until 10:00 AM.
The filter 1 indicator icon will light when filter 1 is running.
The second filter cycle is automatically activated at 8:00 PM and operates the pump until 10:00 PM.
The filter 2 indicator icon will light when filter 2 is running.

Clean-up Cycle (optional)
When the pump is turned on by a button press, a clean-up cycle begins 30 minutes after the pump
is turned off or times out. The pump and the ozone generator will run for one hour.

Ozone
On most systems, the ozone generator (if installed) runs during filter cycles (except when pump 1
is operating at high speed on a a non-circ system) and during clean-up cycles.
On some systems, the ozone generator operates whenever the pump runs.
If your system is configured with the optional ozone suppress feature, the ozone generator will turn off
for 1 hour any time a function button (Jets 1, Jets 2, etc.) is pressed. Ozone enabled is indicated by the
O3 icon on the display.

Freeze Protection
If the temperature sensors detect a drop to 44˚F (approximately 6.7˚C) within the heater, then the
pump automatically activates to provide freeze protection. The equipment stays on until 4 minutes
after the sensors detect that the spa temperature has risen to 45˚F (approximately 7.2˚C) or higher.
In colder climates, an optional additional freeze sensor may be added to protect against freeze
conditions that may not be sensed by the standard sensors. Aux freeze sensor protection acts similarly
except with the temperature thresholds determined by the switch and without a 4-minute delay
in turnoff. See your dealer for details.

Locking the Panel (PL)
Press “Time” “Jets 1” then “Warm” within 3 seconds. When locked, the PL indicator light will light. All
buttons are frozen except the “Time” button. To unlock the panel, press “Time” “Jets 1” then “Cool.”

Locking the Set Temperature (TL)
Press “Warm” or “Cool” then “Time,” “Jets 1,” and “Warm” within 3 seconds to activate the lock.
The TL indicator light will light when the set temperature is locked.
To unlock the set temperature, press “Warm” or “Cool” then “Time”, “Jets 1” and “Cool.”
